Abstract
This invention is a reclining chair which includes a seat portion with a back portion and a leg portion pivotably connected thereto. An arm rest pivotably interconnects the back portion with a leg portion with suspension points being provided at both the back and leg portions. The rotation relationship between leg and back portions at their respective pivots to the seat portion is approximately two to one.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A reclining chair comprising: a seat portion having a bottom, a front area and a rear area; a back rest poriton pivotably connected to the rear area of said seat portion and movable from a generally upright position to a downward reclined position; a leg rest portion pivotably connected at a point intermediate its ends to the front area of said seat portion and movable from a tucked position underneath the bottom of said seat portion to an extended position where the leg rest portion extends outwardly from the front area of said seat portion; arm rest means pivotably said back rest portion and to one end of said leg rest portion and operative to move said back rest portion from said generally upright position to said downward reclined position in response to said leg rest portion being moved from said tucked position to said extended position and first and second support means, said first support means connected to said back rest portion and said second support means connected to said leg rest portion with said second support means being connected to said leg rest portion at a point thereon between the other end of said leg rest portion and the pivotal connection of said leg rest portion and said seat portion; and wherein the seat portion, back rest portion, leg rest portion, and arm rest means are so proportioned that the angle of pivot of said leg rest portion as compared to said back rest portion is a ratio of approximately two to one, whereby a comfortable, easily adjustable reclining chair is provided wherein the leg rest portion is pivoted up against the bottom of the seat portion when the back rest portion is in maximum upright position and is outwardly extending from said seat portion when said back rest portion is reclined.
2. The reclining chair of claim 1 wherein the maximum ratio of pivot angles is approximately 150 degrees to 75 degrees.
3. The reclining chair of claim 1 wherein the minimum ratio of pivot angles is approximately 110 degrees to 55 degrees.
4. The reclining chair of claim 1 wherein the ratio of pivot angles is in the range from 150 degrees/75 to 110 degrees/55 degrees.
5. The reclining chair of claim 1 wherein an elongated fabric supports the body of the user of the chair.
6. The reclining chair of claim 1 wherein said support means is collapsible for more ready transport and storage.Cited by (0)
